Environment

Release : 12.8.05

Resolution

Follow below steps to parse the non English characters.

Navigate to (sps_home)\proxy-engine\conf and open the SmSpsProxyEngine.properties file 

- Add the following in the NETE_SPS_PROXYENGINE_CMD section before the classpath: 

-Dhttp_protocol_element_charset="UTF-8" ---) to be added 

For example: 


NETE_SPS_PROXYENGINE_CMD="%NETE_SPS_JAVA_HOME%\bin\java.exe" -Xms512m -Xmx1024m -XX:MaxMetaspaceSize=256M -Dhttp_protocol_element_charset="UTF-8" 

Note : Here UTF-8 is the character set that our noodle client uses while communicating with back end server.
